The higher efficiency of the brushless motor, combines with the super charge capacity of the 5.0Ah batteries to deliver what one vendor describes as unbeatable runtime.

In addition to “class-leading performance,” Dewalt says that their new cordless brushless rotary hammers offer “the lowest vibration level in the category.”

There’s no word yet as to whether these will be released in the USA, but if they are, then they will probably be announced at the 2015 World of Concrete show in early February.

Update: They’re out now!

The new brushless rotary hammers are welcome additions to the 18V XR/20V Max cordless lineup, and a few comments in our “are you happy with Dewalt’s 20V Max progress post” suggest that we’re likely to see more brushless developments in coming months.

I carry more than 7lbs in my tool belt here and there so I don’t see the big deal there. I don’t know if other brands sell standalone work tool belts (just the belt alone with out the side storage pockets) but I bought a dewalt leather belt that is 2” thick/wide…..from my experience with dressing leather belts, leather belts can handle a lot of weight. So a 2” wide leather belt should be enough for more than 7lb of weight.

The bigger issue about carrying weight on your hip is throwing your body off balance and can affect your hip joints if you walk a lot. The solution to that is to balance the hips by using the same amount of weight on the other side. Or you could hook it on the back or hook it on each all side randomly. By like I said, 7lbs does not seem excessive to me. Either way being on a latter drilling holes, the hook can be used for the tool to be hanged on the latter itself.

They finally come out with a charging station that charges more then 1 battery at a time, something dewalt did last year, a rehash of their tape measure, the m12 fuel saw and that vacuum… Only tool there worth anything is the m12 saw

My 36 volt version is still hammering away. I since fitted it with an onboard dust collector that came out quite a few years later, so unless i start hiring a crew or something, I’m set. Looks like a nice tool, though.

Zero information to be found on a potential US release… My 253 is getting up there, and I’m anxiously holding out to retire it with this guy. Is there any information regarding a 20v release that you’re aware of since this post?
